Specification of Letters Patent.

Patented oct. 27, 190s.

Application filed November 26, 1907. Serial No. 403,939.

To all whom 'it may concern:

Be 1tI known that I. DANmL'Cirisn. a citiyzen of the Fuited `States. residing at New York city.l in the county of Kings and State of New i ork.have invented certain new and useful Improvements in Belt-Couplers: and

I do hereby declare the following to be a full,

clear, and exact description of the invention.

such as will enable others skilled in the art to whlchit appertams'to make and use the same.

This invention relates to improvements in belt couplers and comprises improved p1votally mounted members hinged together for lVith these and other objects in view the invention comprises certain novel constructions7 combinations, and arrangement of parts that will be hereinafter more fully described and claimed.

In the accompanyingdra-Wing: Figure 1' is a perspective view of my improved coupler secured to a belt. Fig. 2 is a plan View of my improved couplelz Fig; 3 is a section of Fig. 2 on line 3'3. Fig. 4 is a 'plan viev7 of a blank forming half or one part of my im; proved coupler. l

In constructing a coupler according to the present invention I have designed to make the saine preferably of lstrong steel and yet so arranged as to be comparatively light in Weight. Y t

'In constructing the parts of the coupler the same are 'stamped fromsheet metaland only require bending for forming an opening for the reception ofa shaft or pintle before being'completed, ready for use. y

Referring more particularly to the drawing 1 indicates one-half of the coupler and 2 the remaining half secured together by aI pintle 3. The members 1 and 2 are'made identical so as to fit together when completed as seen in Figs. 1 and 2.. In constructing a coupler the members 1 and 2 are stamped,

the same from sheet metal and form a blank 'as seen in Fig. 4f In stamping the metal. openings i are provided and also bars or strips These are of considerable lengt-h so as to forni an opening through which a pintle :i is designed to pass when the end 6 of the blank is folded over against end T. The holes or apertures S in the end G are designed to be of a larger size than holes or apertures 9 in the end 7 sotliat all theA holes or apertures may be punched at one time before turning or forming the blank into a completed coupler.'

T heforming of holes or apertures @larger ,v

than the. remaining apertures permits a leen'ny when turning the blank so that if the holes or apertures do not exactly register. 1

the size of apertures 8 will permit rivets or securing means 1() to pass through both apertures Without difficulty. This obviates the necessity of turning over the end 6 against the end 7 before punching, and consequently saves the necessity of punching holes through tivo thicknesses of metal. Projecting from end 7 is alug or extension 11 formed with. apertures 12 for acbommodating securing means as rivets 13 Which are .designed to be passed through apertures 12 and through j the belt to assist rivets 1() in holding the coupler in position.

In assembling the coupler two blanks as shown in Fig. 4: are taken and the end 6 of each blank turned over so as to be in the position shown in Fig. 3. It Will be observed` that the end 6 does not extend over to extension 11 but extends simply far enough for holes or apertures 8 to register with apertures 9. This will save material and also permit the couplers to be made considerably lighter with equal strength. .After the t-Wo blanks have been folded or turned the strips or bars 5 in one of the blanks is inserted into the apertures or slots 4: of the other blank and pintle 3 passes through the two blanks thus uniting the 'same and presenting a complete coupler as seen in Fig. 2. The securing means or rivets 10 and 13 are designed to be passed through the belt as seen 1n Figs. 1 and 3 for firmly holding the coupler in position. When two of the blanks have been securedtogether by pintle 3 as just set forth a hinged portion or extension 14 isprovided. The hinged portion 14 in securing the coup,` ler in place is designed to beplaced between the ends of the belt as seen in Fig. 3. It

will also be observedthat iny placing the'llo ing lugs or member 1l as anextension con coupler in position on the belt thelugs or extensions 1l are bent .so as to be in' the same plane as the end 4(3. In-this Way the*v coupler contacts with the belt substantially from pintle 3 to the'eXtreme endoi:l the coupler.

In constructing a' coupler according to the present invention the openings 4: are de-v signed to be stamped out and to extend as near the apertures t8 and 9 as possible With- 'out weakening the coupler. By'euttingont the metal between openings 12 and by formvsiderabl'e material is dispensed with, and

ally'mounted' plates, each of said plates being formed from a single piece of materialand folded upon itself to 'form a pintle receiving portion and being' again deiiected until its inner edge 1s ina plane with the `outer edge of the. folded portion, and a pintle passing through said plates for pivotally securing the same together.

2. In a belt coupler, a plurality oftplates, means for pivotally securing same together and means for securing said plates to. said belt, eachl of said plates being stamped from a single piece of sheet metal and formed .with elongated bars designed to be bent .for receiving said pintle and an extension fo'rnied on one edge of each of said plates bent for taking'a position in the same plane as the end of that portion ofthe plate that is bent over for forming -a -pintle receiving portion.

In testimony whereof I aix my signature in presence of two Witnesses.
